Home Health Billing — Built for Your Practice
Home health payment changed structurally in 2020, and a lot of agencies are still billing like it didn't. PDGM prices every 30-day period on OASIS-E assessment data — not visit volume — which means a single conservatively-scored functional item can quietly push an entire period into a lower-paying clinical group, and no amount of correct claim-form work recovers that lost reimbursement after the fact.
Layered on top of that are hard deadlines that exist independently of the payment model: the Notice of Admission due within 5 calendar days of the start of care or the agency eats a payment penalty for every day of delay, and the LUPA visit-count threshold that can collapse a full episode payment into a handful of per-visit fee-schedule payments if visit counts fall short. Our home health billing team manages OASIS-E accuracy review, PDGM clinical grouping, face-to-face and certification tracking, NOA timing, and LUPA threshold monitoring as one integrated workflow, not five separate checklists.
What's Costing Home Health Practices Money Right Now
These are the specific, avoidable spots where home health revenue quietly disappears before a claim ever gets appealed.
A conservatively scored OASIS-E functional item can silently push an entire 30-day period into a lower-paying PDGM clinical group — and it never shows up as a denial, so nobody notices the underpayment.
Missing the 5-day Notice of Admission deadline triggers a payment reduction for every day of delay, with no way to recover it retroactively.
Face-to-face encounter documentation that's generic instead of clinically specific gets treated as a missing requirement on audit — denying the entire episode, not just a line item.
Visit counts that fall below the LUPA threshold for a patient's specific clinical group collapse a full case-mix payment into low per-visit fee-schedule amounts.
Homebound status documentation that doesn't meet Medicare's two-part test invites denial on audit even when the clinical picture clearly supports it.
Private duty and Medicaid per-diem nursing billed through the same workflow as Medicare PPS episodes create mismatched claims across three completely different payment tracks.
Top Home Health Claim Denial Reasons — and How We Eliminate Them
Most Home Health denials are preventable. Our team knows exactly what to look for before submission.
❌ OASIS-E Functional Item Coding Understates Impairment, Downgrading PDGM Group
PDGM's functional impairment level — one of the primary drivers of the 30-day payment rate — is calculated directly from OASIS-E GG-series mobility and self-care items. A field clinician who codes a patient as more independent than they actually are (a common conservative-scoring tendency) can shift the entire period into a lower-paying functional level, and because this happens at the assessment stage, it never shows up as a "denial" on a claim — the practice simply gets paid less for the same clinical acuity, period after period, without ever seeing an EOB that flags it.
✓ Our Fix
We review OASIS-E functional and clinical items for internal consistency against the visit documentation before the assessment locks, catching under-scoring and coding gaps that would otherwise silently suppress the PDGM payment rate for the entire period.
❌ Notice of Admission Filed Late
The Notice of Admission must be submitted within 5 calendar days of the start of care. Miss that window and Medicare reduces payment for every day between the start of care and the date the NOA is actually filed — a penalty with no retroactive cure once the window has passed.
✓ Our Fix
We track the start-of-care date for every admission against the 5-day NOA deadline and submit before the window closes, eliminating this entirely avoidable payment reduction.
❌ Face-to-Face Encounter Documentation Doesn't Clinically Support Certification
The face-to-face encounter occurred within the required window, but the physician's documentation is generic and doesn't specifically support the homebound status and skilled-need determination the certification is attesting to. On audit, this is treated as a missing face-to-face requirement even though the visit technically happened — resulting in denial of the entire episode, not just a line item.
✓ Our Fix
We review face-to-face documentation content, not just its timing, and flag encounters where the clinical narrative doesn't adequately support certification before the claim is submitted — giving the agency a chance to obtain a corrected note.
❌ LUPA Threshold Missed for the Patient's Specific Clinical Group
Each PDGM clinical group has its own LUPA visit-count threshold — it is not a single fixed number across all patients. A coordinator tracking visits against a generic threshold assumption, rather than the threshold for that patient's actual assigned clinical group, can miss that a period is at risk until the low per-visit payment already occurred.
✓ Our Fix
We calculate the specific LUPA threshold for each patient's assigned PDGM clinical group and alert agency coordinators when visit counts approach that group's specific threshold — not a generic rule of thumb.
Our Home Health Billing Process, Start to Finish
OASIS-E & Charge Capture Accuracy
We review OASIS-E functional and clinical items for internal consistency against visit documentation before the assessment locks, and code every 30-day period to the clinical group the documentation actually supports.
Eligibility & Certification Verification
We verify Medicare home health eligibility, homebound status against the two-part test, and physician face-to-face and certification documentation before the episode bills.
Compliance & Timing Audits
Every admission is tracked against the 5-day Notice of Admission deadline, and every patient's visit count is tracked against their specific PDGM clinical group's LUPA threshold.
Denial Prevention & Recovery
Face-to-face documentation is reviewed for clinical content, not just timing, and any denial that still occurs is tracked, corrected at the root, and appealed.

We Partner With Every Type of Home Health Practice
Medicare-Certified Home Health Agencies
Full PDGM billing workflow — OASIS-E accuracy review, clinical grouping, NOA timing, and LUPA threshold tracking — for standard Medicare-certified episodes.
Hospice Programs
Physician supervision (G0182) and per-diem nursing billing managed on its own certification and recertification cadence, separate from the PDGM/OASIS workflow.
Private Duty Nursing Agencies
Medicaid per-diem T-code billing and commercial hourly private duty authorization tracked separately from the Medicare PPS episode workflow.
Post-Acute / Institutional-Referral Agencies
Admission-source tracking for patients referred directly from a hospital or SNF stay, since PDGM prices institutional-source periods differently from community admissions.
Community-Admission Home Health Agencies
PDGM clinical grouping and functional impairment scoring built for patients admitted directly from the community rather than following an institutional stay.
Multi-Branch Home Health Groups
NOA timing, LUPA threshold monitoring, and face-to-face documentation tracked consistently across every branch location and every admission.

The Patient-Driven Groupings Model prices each 30-day payment period using four variables: the clinical grouping derived from the principal home health diagnosis, a functional impairment level calculated from OASIS-E GG-series mobility and self-care items, a comorbidity adjustment based on secondary diagnoses, and the admission source and timing (whether the period follows an institutional stay or starts in the community, and whether it's an early or later period in the sequence). There is no therapy-visit-volume component at all — a functional score that's coded even slightly too high (indicating more independence than the patient actually has) can push the entire period into a lower-paying clinical group before a single claim line is generated.
The Notice of Admission (NOA), which replaced the old Request for Anticipated Payment process, must be submitted to Medicare within 5 calendar days of the start of care. Missing that deadline triggers a payment reduction for every day between the start of care and the date the NOA is actually filed — and that reduction cannot be recovered retroactively once the window has closed. We track every admission's start-of-care date against this 5-day deadline so the NOA goes out before the penalty clock matters.
Medicare requires a face-to-face encounter between the patient and the certifying physician (or an allowed non-physician practitioner) within 90 days before or 30 days after the start of home health care, and the encounter documentation has to clinically support both the homebound determination and the need for skilled services — not just confirm that a visit happened. We review the content of face-to-face documentation, not only its timing, and flag encounters where the clinical narrative is too generic to support certification before the claim goes out.
A Low Utilization Payment Adjustment (LUPA) happens when the number of visits in a 30-day payment period falls below the visit-count threshold for that patient's specific PDGM clinical group — and that threshold varies by group, typically in the 2-to-6-visit range, rather than being one fixed number for every patient. Falling below it converts payment from the full case-mix-adjusted period rate to low per-visit fee-schedule amounts. We calculate the actual threshold for each patient's assigned clinical group and alert coordinators as visit counts approach it, rather than tracking against a generic rule of thumb.
Yes. Private duty home health runs on entirely different billing mechanics than Medicare PPS: Medicaid private duty nursing typically bills per-diem or per-visit T-codes, commercial payers often authorize and pay hourly private duty nursing, and non-covered private duty services are self-pay. We handle all three billing tracks separately from the PDGM/OASIS workflow used for Medicare-certified episodes.
Medicare's homebound test has two parts, and both need to be documented, not just implied: the patient must need considerable and taxing effort or assistance to leave home due to illness or injury, and any absences from home must be infrequent, of short duration, or for medical treatment or religious services. A chart that lists a diagnosis without documenting the actual functional limitation and effort required to leave home doesn't meet the standard, even when the clinical picture would otherwise support it. We review homebound documentation against both parts of the test before the episode bills.
These are two different clocks running at the same time. PDGM pays home health care in 30-day payment periods, but physician certification of eligibility still runs on a 60-day certification period — meaning one certification period covers two 30-day payment periods. Recertification is required every subsequent 60 days that care continues, independent of how many 30-day payment periods have billed in between. We track certification and recertification timing on its own 60-day cadence so a payment period never bills against an expired certification.
